So there's a unicorn (winged too I think) horse colt and a little billy goat kit (he's pretty mean and tough guy acting) and the unicorn I think is trying to get home, and along the way kinda makes friends with the goat, but the goat really wants the unicorn horn for himself (apparently it's detachable) and he gets it for a while then feels guilty that he's using the unicorns horn and gives it back (cause that's the source of the unicorn's power I think)

that's all I remember, the most vivid scene is where the goat's just sitting on a cliff with the horn on his head laying next to a sand timer just kickin' it.

hope somebody knows...
